AM-319(-20) Battery Replacement
The AM-319(-20) board uses two three-volt lithium batteries (part #BR1225). The batteries are slightly
smaller than a dime, and are secured side-by-side in a plastic holder. When the batteries need
replacement, you must replace both batteries at the same time. Refer to the following steps and
illustration for battery replacement.
Use extreme care when replacing the batteries! The plastic holder can be easily broken if you
use excessive force!
1. Insert a small scribe or Xacto™ knife from the top, down through the square hole between the
right edge of the battery and the plastic holder’s top piece. (The right side is the side toward
resistor pack RN12).
2. Gently pry the right side of the battery so it slides to the left and pushes against the left side
spring contacts.
3. As you slide the battery to the left and it clears the plastic top hole, pry the right edge of the
battery upward and out through the hole in the top. The battery will typically “pop” up and out.

AM-319(-20) Backup Battery Removal
4. Inspect the battery contacts and be sure they are clean before installing the new batteries. Use
alcohol and a cotton swab to clean if necessary.
5. To install a new battery, insert the edge of the battery down through the square hole and under
the left side of the plastic top. Be sure to install the new batteries with the (+) positive side up.
6. Use your finger to slide the battery to the left and down, until the right edge of the battery slips
under the right side of the plastic top. Release the battery and it should spring to the right,
securing itself under the holder’s top piece.
